Yes, but if its inability to properly grok --option="" is the only
reason we want to add a dependency, wouldn't it suffice to simply
state in the documentation (1) how to recognise the symptom to see
if the version the user has is too old, e.g. "if you see this error
message", "run 'perl -v' to see if your perl is older than X",
etc. and (2) how to work it around, i.e. "instead of giving an empty
value with --option='', say --option ''"?
